Germany warns of anti-migrant backlash after week of bloodshed

Germany warned Monday of a potential backlash against migrants after a Syrian asylum seeker blew himself up outside a music festival, capping a week of attacks that has shaken the country.

The 27-year-old attacker wounded more than a dozen people in the southern city of Ansbach Sunday night and had spent time in a psychiatric facility, regional authorities said.

Berlin said there was as yet "no credible evidence" of a link to Islamic extremism.

Europe's economic powerhouse was already reeling after nine people died in a shopping centre shooting rampage in Munich on Friday and four people were wounded in an axe attack on a train in Wuerzburg on July 18.
